Specification of Letters Patent.

Patented Feb. 19, 1907.

Application tiled March 30, 1906. Serial No. 308.899.

Be it known that I, ARMAND LEJEUNF., a subject of Belgium, residing at Mons en Baroeul, 228 Rue de Roubaix, Nord, France, have invented new and useful Improvements in Fleece-Dividing Apparatus, of which the following is a specification.

This invention relates to continuous fleecedividing apparatus consisting of straps passing over rollers, and is distinguished by the fact that the fleece is seized by the straps immediately it leaves the dofHng-cylinder and is supported by the straps throughout the whole of its travel to the rubbers, whereby the objections pertaining to continuous dividers as heretofore constructed and arising from the fact that the straps in certain portions of their travel only carry the fleece or the slivers along by sinple adherence without serving as a support to them are overcome.

T 0 this end the invention consists, essentially, in the employment of a single dividing-roller provided with deep grooves in which disks or wheels freely turn in the same direction as the dividing-roller, the projections or flanges of the latter, as well as the surfaces of the disks, having the straps passed around them at the bottom part, so that the straps keep the slivers between them and the surface of the projections or flanges of the dividing-roller and the surface of the disks, and thus conduct them to the rubbers.

In the accompanying drawings, Figure 1 is a diagrammatic view of the entire arrangement of my fleece-dividing apparatus, show ing the travel of the straps; and F 2 is a front elevation of the dividing-roller, showing the disks or wheels placed in the grooves thereof.

The apparatus comprises a single dividingroller 1, provided with deep grooves 2, in which are located the disks 3, supported by one of the sets of straps 4, which as they leave the grooves 2 of the dividing-roller 1 pass over guide-pulleys 5 and 6, arranged so as to prevent the disks 3 from leaving the grooves 2 under the drawing action exerted upon the straps 4 by a tension-roller 7, placed below the dividing-roller 1, and over which the straps 4 pass after having passed over an upper guide-roller S, arranged near the upper rubbers 9.

The projections or fianges 10 of the dividing-roller l, formed between the grooves 2, have another set of straps 11 passing round them and also passing over one of the guidepulleys 5 to a roller 12, placed close to the dolling-cylinder 13, so that the Heece as it leaves the dofling-cylinder is immediately supported in its travel between the doffingcylinder and the guide-pulley 5. These straps 11 after having passed over the lower part of the projections or flanges 10 of the dividing-roller 1 pass over a guide-roller 14, which conducts them to the lower rubbers 15. They afterward pass over a lower tension-roller 16 to the guide-roller 12.

It will be easily understood that with the above-described arrangement the fleece coming from the do'fling-cylindcr 13 is supported by the straps 11 directly it leaves the doflingcylinder. These straps conduct the fleece to the guide pulley 5, over which also pass the straps 4 and in. conjunction with the latter eflect the division at the point 17, where the straps 4 pass around the disks 3, while the straps 11 pass round the projections or 'flanges 10 ofthe dividing-roller 1. The slivers thus 'formed' are respectively maintained between the straps 4 and the disks 3 and between the straps 11 and the projections or -flanges of the dividing-roller 1, and the upper as well as the lower slivers are conducted under absolutely the same conditions to their respective rubbers 9 and 15-that is to say, without ever being on the lower surface of the strap. This arrangement consequently allows of effectually preventing any inequality in the slivers. Moreover, it insures a better division, because the fleece is immediately supported the moment it leaves the do'llingcylinder, thus preventing any deformation at this point. The division is, moreover, further assisted by the elasticity with which the disks 3 are kept pressed against the guidepulleys 5 and 6 by reason of their simple suspension upon the strap and through the fact that the division is effected in the longitudinal direction itself of the fibers.

It will be obvious that this system of dividing apparatus allows of en'iploying flat nontwisted straps. It is besides easily applicable to four-feed division-that is to say, to division in which four sets of rubbers are employed instead of two.

The roller over which the straps pass before reaching the dividing-point can be pro- IOC vided with grooves of a depth nearly equal to the thickness of the straps passing to the rollers, as shown in Fig. 1.

Having thus described my invention, what I claim is i l. In a device of the class described, a dividing-roller provided 'with grooves, disks fitted loosely in said grooves of the dividingroller, and two sets of straps, the straps of one set engaging 'with said disks, and the straps of the other set engaging with the projections of said dividing-roller.

2. In a device of the class described, a dividing-roller, disks fitted loosely to said roller and projecting partially beyond the circumference thereof, straps engaging with said loose disks and cooperating therewith for retaining said disks in position on said dividing-roller, and other straps engaging with the dividing-roller in the intervals between the aforesaid disks.

3. In combination a dividing-roller, grooves in said dividing-roller, disks loosely placed in the grooves of the dividing-roller, guide-pulleys coperatingwith said disks, a set of straps passing round said guide-pulleys and over the lower part of the disks in the grooves of the dividing-roller and a second set of straps passing over the lower part of the projections formed on the dividing-roller between the grooves7 substantially as described and for the purpose set forth.

4. In combination a dividing-roller, circular grooves in said dividing-roller, disks loosely placed in the grooves of the dividingroller, two guide-pulleys adjacent to said disks, a tension-roller placed under the dividing-roller, a set of straps passing over the two guide-pulleys, holding the disks in the grooves of the dividing-roller and passing over the tension-roller anda second set of straps passing over one of the two guide-pulleys and over the lower part of the projections formed on the dividing-roller between the grooves in said roller substantially as described and for the purpose set forth.

5. In combination a dividing-roller, grooves in said roller, disks loosely placed in the grooves of the dividing-roller, two guidepulleys adjacent to said disks, a tensionroller placed under the dividing-roller a set of straps passing over the two guide-pulleys, holding the disks in the grooves of the dividing-roller and passing over the tension-` roller, a set of rubbers to which said straps deliver the slivers, a dofling-cylinder of a carding-engine, a guide-roller adjacent to said drifting-cylinder, a second set of straps passing over said guide-roller, over one of the two guide-pulleys and over the lower part of the projections of the dividing-roller, a second guide-roller adjacent to the dividingroller for the said second set of straps, a tension-roller for said second set of straps and a second set of rubbers to which said second set of straps deliver the slivers, substantially as described and for the purpose set forth.

6. In combination, a dividing-roller, grooves in said roller, disks loosely placed in the said grooves and turning in the saine direction as the dividing-roller, a set of straps supporting the said disks, and a second set of straps passing over the lower part of the projections of the dividing-roller, both sets of straps keeping the slivers between them and the surface of the disks and of the projections of the dividing-roller, substantially as described and for the purpose set forth.

In testimony whereof I have signed my name to this specication in the presence of two subscribing witnesses.

ARMAND LEJEUNE.
